Hoop-jack fob



To all whom t may concern: Beit known that.I,` ELMER Fos'mR, of Fairton,in the county 'of Cumberlandand .l State of New'Jersey, have invented anew `and useful Improvement in Rigging for I-Ioisting and Preventing theHoops from Binding onthe Forward Part of the Mast,

` 'calledHoop-Jaekfand I do hereby declare that the following is a full,clear, and

`. eration ofthe same, reference being had t0 `the annexeddrawings,making apart of this lspeciicatiorn` in which-f"` y l Figure 1is"the'oircular space for` the mast;

Fig. 3 is the forward arms oftheband or jack, closed byascrew bolt: Fig. 4 includes thearlns and circle of theujackmadeofironsimilar to the hoops, being frounded` inside `the vlonger armsbeing bedded inthefr edges or sides of the throat l `halyard block.`Fig. jthe rollers forwardA and "aft of the mast to prevent the' jackfrom binding andto or runon the mast,

to which it is properly rigged. Fig. 7 is the brace line and hookconnected to the after screw bolt, the same as Fig. 6, this brace lineprevents the halyards from binding `plate 2 is a bolt hinge and clevispin, connecting the forward part of the hoop as in hoop line of Fig. 6,to which the hoops are seized `which may be substituted in place oi theclevis and roller attached to Fig. 6. Fig. l1 shows the hoop line asconnected to the hoops on the mast by being seized to the hoops inequal' distance on the hoop line as vthehoops are seized to the sail sorigged with hoops. This hoop line may be fastened :to the hoops inditerent ways, the one in the drawing is suggested to be knotted at theproper length apart Jfor the hoops as on the`sail, with two single roundknots at the place of seizing to the hoop, that the bendling twine maynot slip up or down on the hoop line.

`That I claim as my invention and desire to secure by Letters Patent is-The arrangement of the hoop jack with the lower halyard block, the braceline, clevis and gait-hook, clevis and hoop line extending down to thefoot of the mast and connected to each sail hoop, as herein set forth.
